May 182011

In my post “6 microblogging client for Linux” I’ve received a comment about the software: Turpial.
Turpial is a client for Twitter and Identi.ca (only after the 1.4.X release) based on PyGTK, I’ve tested on my ubuntu 11.04 the version available in the development PPA for Ubuntu and so I’ve made the tests on Twitter and Identi.ca.

A signal is an event sent by the kernel to a running program.

The signals can arrive at any time and software can choose what to do when it arrives: it can decide to ignore it or may decide to execute a signal handler and continue with what he did.
